For the first time, scientists have measured the rate at which high-energy neutrinos are absorbed by our planet, a development that could lead to discoveries about physics and the Earth.
Pakistan does not have a long history of domestic particle physics experiments, but the country is nevertheless finding ways to contribute to international efforts.
The Tevatron accelerator at Fermilab set a world record on Sunday afternoon, July 3, 1983, achieving a beam energy of 512 billion electronvolts (GeV). Accelerator operators had made the first-ever attempt at accelerating a beam in the Tevatron at 3:12 a.m. that day, reaching 250 GeV.
Here they measure the time not in minutes or hours. Instead they think in terms of how many antiprotons are ready to stack and how soon the Tevatron will be ready to accept new beam. Or how fast they need to fix something, any time of the day or night. Or how long they can stay awake.
A newly structured High Energy Physics Advisory Panel met in Washington, DC, to provide advice to the Department of Energy and National Science Foundation and to hear science policy-makers’ responses to the President’s budget request.
A surgeon and a scratch golfer most of his adult life, a US Army officer in World War II, the doctor gave up his medical practice in his 60s while exhibiting increasingly erratic behavior–such as meandering down to a favorite car dealer in his prosperous New Jersey town, and signing the pap
